2008 derbi clutch problem

Hi, this is my bike. Over the past few weeks I've noticed that whenever it's in gear with the clutch lever pressed (mostly when slowing down or downshifting) it constantly dies.
Runs fine and the clutch seems to work just fine when taking off. Also, when the engine is not working and I put it in gear and try to roll it off (with the clutch pressed ofc) it acts as if I'm not pressing it....
Hope the clutch is not doomed because I don't have money for a new clutch kit...
And to mention: I haven't done the gearbox oil change since I got it (2 months since I got it). I was gonna change it tomorrow hoping it would fix it..

My derbi senda is constantly getting flooded and I suspect the carburetor.
Today I cleaned my sparkplug and got excess gas out the engine by kicking it a few times, I put the spark plus in after couple of minutes. I gave it a few kicks with the gas off to make sure, but the second I turned on the gas and kicked it around 4 times, I literally began smelling like gas and when I took the spark plug out, it was wet.
The carburetor is a 17.5mm Dellorto PHBG replica (it has no code and no brand name on it) and I'm saying it's a phbg because the design is identical.
Btw I cleaned the carb a few weeks ago but didn't ride much. How can the float/needle get stuck so oftenly? Is it because of the knockoff carb?
Shoukd I buy a genuine dellorto phbg 19mm? I'm planning to buy 70cc soon too so why not.

UPDATE: I saw many of you telling me that I have the wrong spark plug so I bought a new BR9ES for 4 bucks and damn does it run like a charm.
Almost started first kick (forgot the gas off) but by the third kick it ran like a charm!
Thanks to all of you for your help. And thank God I put this picture with the plug because otherwise I wouldn't have known!
Should I still be concerned about the carburetor by now? Is it better to be safe and buy a genuine PHBG or just run it like this temporarily until the problem reappears?

I have a derbi senda drd xtreme 2008 and I want to do a complete tune-up.
My stock exhaust is kinda dead in pretty much all rom rang so I need one that does well in low/mid rom's for offroad.
I'm planning to install a 70cc airsal aluminium kit with a 19mm PHBG carburetor and a exhaust.
So straight to the point: recommend me a good 2 stroke exhaust that doesn't need high rpm, does well in mid rpm and is a high mount (left side)

Hi, I wanna know what bearings derbi senda's (2000-2010) use because I want to replace my rear wheel bearings.

I attached the video cuz I didn't know what to put.

Any advice is helpful!

Why is my 2008 derbi senda 50cc constantly flooding the engine?

It used to start with a solid 4-5 kicks but now it looks like it's trying but doesn't start at all. It started this morning on the 2nd kick but I ran kinda funny, and when I took the sparkplug off and cranked it to get the excess gas out, I was literally full and it kinda splashed me.

I have tried atleast 5 times to rake the plug off, clean it (it still has a consistent blue spark) and then put it in but nothing

Btw, my main jet is 70 and my carb is a 17.5mm Dellorto PHBG (replica).
